Features of SR-DM120/SR-DM160
The MPPT (maximum power point tracking) solar charge controller is
an intelligent, efficient, high-speed solar charge controller with
advanced maximum power point tracking algorithm, which can harvest
the maximum power from the solar array to charge batteries and can
be applied for flexible such as off-frid PV systems.
